2 Ways to Calibrate Android Smartphone Battery

(Last Updated On: May 2, 2017)

Hello, I know it’s been a while I posted a new article here, I apologise for that. So I came up with this awesome post that guides you through how you can restore that lasting ability your android smartphone battery had during the earlier period of its life.

So how is that possible you ask? Well, it is, and I’ll make this post very simple so you’d be able to understand it.

When it comes to rechargeable batteries there are a lot of variations. But one thing that is true for all rechargeable batteries is that, from the day they’re first used … they start to lose their ability to hold the charge. The rate of loss of charge depends on the battery type.

Different Types of Batteries

Nickel Cadmium (NiCd) — mature and well understood but relatively low in energy density. The NiCd is used where long life, high discharge rate and economical price are important. Main applications are two-way radios, biomedical equipment, professional video cameras and power tools. The NiCd contains toxic metals and is environmentally unfriendly.

Nickel-Metal Hydride (NiMH) — has a higher energy density compared to the NiCd at the expense of reduced cycle life. NiMH contains no toxic metals. Applications include mobile phones and laptop computers.

Lead Acid — most economical for larger power applications where weight is of little concern. The lead-acid battery is the preferred choice for hospital equipment, wheelchairs, emergency lighting and UPS systems.

Lithium Ion (Li‑ion) — fastest growing battery system. Li‑ion is used where high-energy density and lightweight is of prime importance. The technology is fragile and a protection circuit is required to assure safety. Applications include notebook computers and cellular phones.

Lithium Ion Polymer (Li‑ion polymer) — offers the attributes of the Li-ion in ultra-slim geometry and simplified packaging. Main applications are mobile phones.

Different battery types adopted from Battery University.

Lithium-ion or Li-ion batteries are the current most popular types of rechargeable batteries used by electronic gadgets. And for smaller slimmer gadgets like our mobile phones, manufacturers mostly use Lithium Ion Polymer(Li-on polymer).

Battery Fact to Note:

Quite often, it’s not the battery that’s malfunctioning, but the way the Android operating system (OS) is collecting and displaying information about our battery’s usage. Recalibration solves this problem.

How do I know my Battery needs Recalibration?

  1. If you’ve ever noticed that your battery drains way too quickly than normal.
  2. If your battery zooms from a full charge to half-full to near empty in what seems like an instant.
  3.  You plugged in your charger and then unplugged it only to see what you thought was 100% is actually only 93%.
  4. You flashed a new ROM and noticed your battery life is now bad.
  5. Updated your Android version.
  6. You did a Factory Settings restore on your phone.

It means that your phone battery may not be displaying the correct charge amount —which means it may not be properly calibrated and needs to be recalibrated.

How to Calibrate your Android Battery (with Root Access)

I recommend using Battery Calibration [ROOT]  (Playstore link).

Steps to do a good battery calibration:

Battery calibration app

1) Download the app from playstore.                                                                                  2) Plug in your phone to the charger.
2) Charge your phone up to 100 percent.
3) Click on the ‘Calibrate your Battery‘ button.
4) Unplug your phone.

 

What this app does is that it removes the BATTERYSTATS.BIN file then lets the android OS generate a new and clean BATTERYSTATS.BIN, so any invalid information (from the previous ROM) is removed.

It is suggested, but not needed, to let the phone fully discharge, calibrate and the let your phone charge to 100% without interruption.

Calibrate your Android Battery (without Root Access)

No app is needed here, just follow the simple steps below.

 

  1. Leave/use your phone until it automatically shuts down.
  2. With the phone still switched off, plug in the charger and bring the battery back up to 100%
  3. At this point, unplug your phone and allow the battery to drain completely.
  4. Once drained completely, plug your charger back in and charge your battery fully to 100% again. That’s it, the phone should be recalibrated.

So I followed your steps on calibrating with root access and I can see some notable changes, not sure yet.

Hello. In this post you recomend for root cell phones to use BATTERY CALIBRATION APLICATION (from NéMa v1.2 I guess); however today june 2.017 they offer the v2.2 that does not needs root permissions. Could you please give your advise about this topic? Thanks. Vicente.
